Application filed June16, 1917. Serial No. 175,132.

To all whom it may concern:

Be it known that I, JOHN A. KERNPHAN, a subject of the British Empire,residlng at Saranac Lake, in the county of Franklin and' State of NewYork, have invented certain to a combined cooling and car heatingsystem. One object of the present inventlon resides in certain im'rovements in the manner of directing and rawing a current of air pastthe engine cylinders. Otherobjects reside in the provision of means forheating the carby means of the air which has been warmed in passing theengine cylinders.

In the drawings- Figure 1 shows in elevation an automobile in which myimprovements are incorporated.

'Fig. 2 shows a detail cross. sectional view of the motor and shows thepaths of the air cooling currents. s

In more detail in the drawings-- a M is a motor'having cylinders 10, 11,12 and 13. These cylinders may be provided withcooling fans, if desired.B is the body of the car having a drivers compartment D and a tonneau T.H is a hood and R is a gratin at the front of the hood which is shapedin semblance of the usual water radiator. Carried by the base of themotor and projecting upwardly therefrom are two sheet metal plates 15,16, having a sinuous contour, as learly shown in Fig. 2. A top plate 17is secured to and bridges the side plates and is also secured to thecylinders 10, 11, '12 and 13. Plates 15, 16 and 17 form a chamber aboutthe engine cylinders. The

front of this chamber carries two concentric funnels18- and 19,,the imir funnel having a tube extending rearward y and upwardly, as shown at20. Within the forward end of funnel 18 is a fan 21 which is revolublysupported upon a bracket carried b the screen structure. The fan issuitably. riven by a belt which is rotated by the engine crankshaft. Atthe front of the first cylinder 10 is a baflle 22 which prevents theair: currents from impinging directly upon the; forward portion of the.first cylinder. I alsoprovide a curved bailie late 23 which extends fromthe side of cyhnder 10, to the side of cylinder 12. This bafile servesto direct a portion of the cool air current directl from the front ofthe casing to the rear cy ders 12 and 14. I have found that theconcentric funnels introduce decided advantages in the proper cooling ofthe cylinders as they make the air currents set up by the fan moreuniform in the intensity of flow at difierent places. The bafiles 22 and23 also cooperate to uniformly cool the various cylinders instead ofcooling the forward cylinder more than the rear cylinder as has been thecase by means of the ejector exert a considerable suction uponthecooling air'and thereby aid the fan in cooling the engine.

(Jar heating devices.

Connected with duct 24 are branch ducts 27 and 28 which extend to thetonneau T and the drivers compartment D, respectively. These ductsterminate at suitable -registers 30 which may be opened or closed atwill to control the entrance of heated air to the driving compartment ortonneau.

For convenience in illustration I have shown duct 24 as being restrictedin area. It will be understood that this duct will be of suitable sizeto conduct. the cooling air out'of the chamber without back pressure.The duct may also pass directly through the dash to the tonneau with adepending branch leading to the ejector.

The mufller pipe 26 is provided'with a Inuffler 31 and leads toa'manifold 32 which it will be noted is above plate 17. Parts 32 arethecylinder heads making them readily removable without removing the plate17. As shown in Fig. 2,,the valve push rods '33 are without the aircasing. The feature of having these parts without the air cooling casingI' consider desirable since it elimi-' hates the possibility of oil orexhaust fumes commingllng withthe cooling air. Such a mixture of noxiousfumes and air is undesirable when the air is to be used for heatingpurposes. V

It will be understood that. my invention may be modified in various waysas will occur to those skilled in the art.

gitudinally disposed cylinders within the hood. a casing surrounding thesame, having an air inlet opening in front for cooling air and an outletin the rear for the egress of air, and battle plates within the casingforming passages for the air, one of said passagesincluding all thecylinders, and the other being adapted to divert a portion of the received air from the front cylinders and directly upon those in the rear.

3. In a device of the class described, in combination, a plurality oflongitudinally disposed cylinders, a longitudinally disposed sinuouscasing inclosing the same, a curved battle in said casing adaptedto'direct cooling air to the rear cylinders without permitting the airto contact with the intervening cyl inders, the aforesaid sinuouscurvature of the casing being also adapted to cooperate to direct thepassage of air through the chamber and about the cylinders.

4. In a device of the class described, in combination, a plurality oflongitudinally disposed cylinders, a longitudinallydisposedsinuouswcasing inclosing the same, a curved battle in saidcasing adapted to direct cooling air to the rear cylinders withoutpermitting the air to contact with the intervening cylraoaooo inders,the aforesaid sinuous curvature of the casing being also adapted tocooperate to direct the passage of air through thechamber and about thecylinders, and apair of concentrically disposed cone-shaped membersassociated with the front of the casing and being adapted to direct theair into the same.

-5. In a device of the class described, in combination, a plurality oflongitudinally disposed cylinders, a longitudinally disposed sinuouscasing inclosing the same, a curved balile in said casing adapted todirect cooling air to the rear cylinders without permitting the air tocontact with the intervening cylinders, the aforesaid sinuous curvatureof the casing being also adapted to cooperate todirect the passage ofair through the chamber and about the cylinders, and a pair ofconcentrically disposed cone-shaped members associated with the front ofthe casing and being adapted .to direct the air into the same, the innerof said cones having an upwardly directed outlet opening to direct aportion of the air upwardly.

6. In an air cooling system for automobile engincs, the combination witha plurality of cylinders within the-hood, casing surrounding the same, apair of concentric cones for directing received air through the casing,a rotary fan for delivering an air blast into the cones, a duct leadingfrom the rear of the casing for carrying off the warmed. air, anin'ector-Iocated in the rear part of said duct. and a mufller pipeassociated with the ejector and leading the exhaust gases from theengine thereto for set-' ting up a suctiomto assist inwithdrawing thewarmed air from the system.

In testimony whereof I affix my signature.
